Clin Infect Dis 2020 73 (5) e1126-e1134 BACKGROUND: The Core Elements of Outpatient Antibiotic Stewardship provide a framework to improve antibiotic use, but evidence supporting safety are limited. We report the impact of Core Elements implementation within Veterans Health Administration sites. METHODS: A quasi-experimental controlled study assessed the effects of an intervention targeting antibiotic prescription for uncomplicated acute respiratory tract infections (ARI). Outcomes included per-visit antibiotic prescribing, treatment appropriateness, potential benefits and complications of reduced antibiotic treatment, and change in ARI diagnoses over a 3-year pre-implementation and 1-year post implementation period. Logistic regression adjusted for covariates [OR (95% CI)] and a difference-in-differences analysis compared outcomes between intervention and control sites. RESULTS: From 2014-2019, there were 16,712 and 51,275 patient-visits in 10 intervention and 40 control sites, respectively. Antibiotic prescribing rates pre-post implementation in intervention sites were 59.7% and 41.5%, respectively; in control sites they were 73.5% and 67.2%, respectively [difference-in-differences p<0.001]. The intervention site pre-post implementation odds ratio to receive appropriate therapy increased [1.67 (1.31, 2.14)] which remained unchanged within control sites [1.04 (0.91, 1.19)]. There was no difference in ARI-related return visits post-implementation [(-1.3% vs. -2.0%; difference-in-differences p=0.76] but all-cause hospitalization was lower within intervention sites [(-0.5% vs. -0.2%); difference-in-differences p=0.02]. The odds ratio to diagnose upper respiratory tract infection not otherwise specified compared to other non-ARI diagnosis increased post-implementation for intervention [1.27(1.21,1.34)] but not control [0.97(0.94,1.01)] sites. CONCLUSIONS: Implementation of the Core Elements was associated with reduced antibiotic prescribing for uncomplicated ARIs and a reduction in hospitalizations. ARI diagnostic coding changes were observed. |
Think twice: A cognitive perspective of an antibiotic timeout intervention to improve antibiotic use
Jones M , Butler J , Graber CJ , Glassman P , Samore MH , Pollack LA , Weir C , Goetz MB . J Biomed Inform 2016 71S S22-S31 OBJECTIVES: To understand clinicians' impressions of and decision-making processes regarding an informatics-supported antibiotic timeout program to re-evaluate the appropriateness of continuing vancomycin and piperacillin/tazobactam. METHODS: We implemented a multi-pronged informatics intervention, based on Dual Process Theory, to prompt discontinuation of unwarranted vancomycin and piperacillin/tazobactam on or after day three in a large Veterans Affairs Medical Center. Two workflow changes were introduced to facilitate cognitive deliberation about continuing antibiotics at day three: 1) teams completed an electronic template note, and 2) a paper summary of clinical and antibiotic-related information was provided to clinical teams. Shortly after starting the intervention, six focus groups were conducted with users or potential users. Interviews were recorded and transcribed. Iterative thematic analysis identified recurrent themes from feedback. RESULTS: Themes that emerged are represented by the following quotations: 1) captures and controls attention ("it reminds us to think about it"), 2) enhances informed and deliberative reasoning ("it makes you think twice"), 3) redirects decision direction ("...because [there was no indication] I just [discontinued] it without even trying"), 4) fosters autonomy and improves team empowerment ("the template... forces the team to really discuss it"), and 5) limits use of emotion-based heuristics ("my clinical concern is high enough I think they need more aggressive therapy..."). CONCLUSIONS: Requiring template completion to continue antibiotics nudged clinicians to re-assess the appropriateness of specified antibiotics. Antibiotic timeouts can encourage deliberation on overprescribed antibiotics without substantially curtailing autonomy. An effective nudge should take into account clinician's time, workflow, and thought processes. |
Taking an Antibiotic Time-out: Utilization and Usability of a Self-Stewardship Time-out Program for Renewal of Vancomycin and Piperacillin-Tazobactam
Graber CJ , Jones MM , Glassman PA , Weir C , Butler J , Nechodom K , Kay CL , Furman AE , Tran TT , Foltz C , Pollack LA , Samore MH , Goetz MB . Hosp Pharm 2015 50 (11) 1011-24 BACKGROUND: Antibiotic time-outs can promote critical thinking and greater attention to reviewing indications for continuation. OBJECTIVE: We pilot tested an antibiotic time-out program at a tertiary care teaching hospital where vancomycin and piperacillin-tazobactam continuation past day 3 had previously required infectious diseases service approval. METHODS: The time-out program consisted of 3 components: (1) an electronic antimicrobial dashboard that aggregated infection-relevant clinical data; (2) a templated note in the electronic medical record that included a structured review of antibiotic indications and that provided automatic approval of continuation of therapy when indicated; and (3) an educational and social marketing campaign. RESULTS: In the first 6 months of program implementation, vancomycin was discontinued by day 5 in 93/145 (64%) courses where a time-out was performed on day 4 versus in 96/199 (48%) 1 year prior (P = .04). Seven vancomycin continuations via template (5% of time-outs) were guideline-discordant by retrospective chart review versus none 1 year prior (P = .002). Piperacillin-tazobactam was discontinued by day 5 in 70/105 (67%) courses versus 58/93 (62%) 1 year prior (P = .55); 9 continuations (9% of time-outs) were guideline-discordant versus two 1 year prior (P = .06). A usability survey completed by 32 physicians demonstrated modest satisfaction with the overall program, antimicrobial dashboard, and renewal templates. CONCLUSIONS: By providing practitioners with clinical informatics support and guidance, the intervention increased provider confidence in making decisions to de-escalate antimicrobial therapy in ambiguous circumstances wherein they previously sought authorization for continuation from an antimicrobial steward. |
Variation in outpatient antibiotic prescribing for acute respiratory infections in the veteran population: a cross-sectional study
Jones BE , Sauer B , Jones MM , Campo J , Damal K , He T , Ying J , Greene T , Goetz MB , Neuhauser MM , Hicks LA , Samore MH . Ann Intern Med 2015 163 (2) 73-80 BACKGROUND: Despite efforts to reduce antibiotic prescribing for acute respiratory infections (ARIs), information on factors that drive prescribing is limited. OBJECTIVE: To examine trends in antibiotic prescribing in the Veterans Affairs population over an 8-year period and to identify patient, provider, and setting sources of variation. DESIGN: Retrospective, cross-sectional study. SETTING: All emergency departments and primary and urgent care clinics in the Veterans Affairs health system. PARTICIPANTS: All patient visits between 2005 and 2012 with primary diagnoses of ARIs that typically had low proportions of bacterial infection. Patients with infections or comorbid conditions that indicated antibiotic use were excluded. MEASUREMENTS: Overall antibiotic prescription; macrolide prescription; and patient, provider, and setting characteristics extracted from the electronic health record. RESULTS: The proportion of 1 million visits with ARI diagnoses that resulted in antibiotic prescriptions increased from 67.5% in 2005 to 69.2% in 2012 (P < 0.001). The proportion of macrolide antibiotics prescribed increased from 36.8% to 47.0% (P < 0.001). Antibiotic prescribing was highest for sinusitis (adjusted proportion, 86%) and bronchitis (85%) and varied little according to fever, age, setting, or comorbid conditions. Substantial variation was identified in prescribing at the provider level: The 10% of providers who prescribed the most antibiotics did so during at least 95% of their ARI visits, and the 10% who prescribed the least did so during 40% or fewer of their ARI visits. LIMITATION: Some clinical data that may have influenced the prescribing decision were missing. CONCLUSION: Veterans with ARIs commonly receive antibiotics, regardless of patient, provider, or setting characteristics. Macrolide use has increased, and substantial variation was identified in antibiotic prescribing at the provider level.

Incidence of medically-attended norovirus-associated acute gastroenteritis in four Veteran's Affairs Medical Center populations in the United States, 2011-2012
Grytdal SP , Rimland D , Shirley SH , Rodriguez-Barradas MC , Goetz MB , Brown ST , Lucero-Obusan C , Holodniy M , Graber C , Parashar U , Vinje J , Lopman B . PLoS One 2015 10 (5) e0126733 An estimated 179 million acute gastroenteritis (AGE) illnesses occur annually in the United States. The role of noroviruses in hospital-related AGE has not been well-documented in the U. S. We estimated the population incidence of community- acquired outpatient and inpatient norovirus AGE encounters, as well as hospital-acquired inpatient norovirus AGE among inpatients at four Veterans Affairs (VA) Medical Centers (VAMCs). Fifty (4%) of 1,160 stool specimens collected ≤7 days from symptom onset tested positive for norovirus. During a one year period, the estimated incidence of outpatient, community- and hospital-acquired inpatient norovirus AGE was 188 cases, 11 cases, and 54 cases/ 100,000 patients, respectively. This study demonstrates the incidence of outpatient and community- and hospital-acquired inpatient norovirus AGE among the VA population seeking care at these four VAMCs. |
